Open a PDF in ReadThisAloud, listen while the current words are highlighted, move through the document without losing your place, and keep control of speed, progress, bookmarks, and playback.
ReadThisAloud Guide • Updated September 2026
A PDF voice reader is most useful when you can do more than press Play. ReadThisAloud keeps the spoken audio connected to the document so you can listen, follow, navigate, and return to important places.
ReadThisAloud extracts available PDF text directly. If a page does not contain enough usable selectable text, the Reader can use local OCR on the pages that need recognition instead of treating every page the same.
Select a voice in the Reader and begin narration. ReadThisAloud prepares long material progressively so useful playback can begin without waiting for an entire long document to be processed first.
Synchronized word highlighting tracks the narration in the read-along view. This makes PDF text to speech easier to follow when you want both audio and visible text together.
Use Find, document sections, click-to-jump navigation, bookmarks, the playback timeline, and the entire-document progress control to move directly to the material you need and resume from there.
When a PDF contains image-based pages, local OCR can recognize the visible printed text on the pages that need it and place that text into the normal Reader workflow.
Reading Mode, text-size controls, line spacing, read-along brightness, and tracking choices let you shape the reading workspace around the document.
After narration is prepared, export it to MP3 when you want an audio copy for later listening outside the Reader.
Open the PDF in ReadThisAloud, choose a voice, and start narration. Synchronized highlighting follows the spoken words while you use navigation and playback controls.
